Hello

My name is Isaac. I have had freshwater tanks for years and have finally decided to dive in to a reef tank. I am very excited and quite nervous. I find that there are MANY opinions to everything in this world and its hard to find the correct advice. I'm hoping to learn and grow in this community, hopefully with some help from others. I have a 50 Gallon tank with a Fluval 70 and a CPR backpack protein skimmer. I have a 4 bulb T5 light. 5 gallons of live sand and about 45lbs of live rock. My tank has been up and running for 2 weeks. I put 2 clown fish in soon after startup and I put a clean up crew of 4 snails, 2 pep. shrimp and 1 hermit crab yesterday.

I'd like to start off with my first question about circulation. I dont have any circ pumps yet and i need to know how many GPH i should have?

Thanks in advance
